I bought a 4 circuit switch and used wire harness from Ebay (so I don't have to slice my original harness) for the purpose of wiring in the dash switch, but never got around to it.
This is what I do with my Civic. I had the problems you had. I had to disable all wires into the alt or the unit did not entirely quit. One problem remained, however, once I turn the unit on from the dash, the only way to turn it back off is by cutting the engine. I decided to live with it because of how often I do EOC, but a better way is certainly available if I figure out how to draw off the extra power keeping the field windings charged.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
